Lighting device having magnetic member and magnet

Abstract

To provide a lighting device where a light-emitting body including light-emitting elements whose light-emitting regions are spread out in a plane or light-emitting elements in which a plurality of light-emitting regions are arranged in a plane can be exchanged easily. To provide a lighting device in which a terminal of the light-emitting body can be electrically connected to a contact of a mounting portion easily. A light-emitting body including light-emitting elements whose light-emitting regions are spread out in a plane or light-emitting elements in which a plurality of light-emitting regions are arranged in a plane may be fixed by a magnetic force so that a terminal of the light-emitting body is in contact with the contact of the mounting portion.

 a mounting portion comprising a magnet, an elastic body, and at least a first contact and a second contact, 
 wherein the magnet and each of the first contact and the second contact are spaced from each other, 
 wherein the elastic body is configured to distance the magnet from the magnetic member in the light-emitting body, 
 wherein the first terminal and the second terminal are configured to be in contact with the first contact and the second contact, respectively, and 
 wherein the light-emitting body is configured to be detachably fixed to the mounting portion by the magnet and the magnetic member. 
 
     
     
       2. The lighting device according to  claim 1 , wherein each of a height of the first contact and a height of the second contact is variable by contact between the light-emitting body and the first contact or the second contact. 
     
     
       3. The lighting device according to  claim 1 , wherein the magnetic member is fixed to the optical member or the sealing member. 
     
     
       4. The lighting device according to  claim 1 , wherein the sealing member comprises the magnetic member. 
     
     
       5. The lighting device according to  claim 1 , wherein the magnetic member comprises iron, cobalt, or manganese. 
     
     
       6. A lighting device comprising:
 a light-emitting body comprising an optical member, a sealing member, at least a first terminal and a second terminal, a light-emitting element sealed between the optical member and the sealing member, and a magnetic member; 
 a mounting portion comprising a magnet, an elastic body and at least a first contact and a second contact; and 
 a spacer on the mounting portion, the spacer being in contact with the light-emitting body, 
 wherein the magnet and each of the first contact and the second contact are spaced from each other, 
 wherein the elastic body is configured to distance the magnet from the magnetic member in the light-emitting body, 
 wherein the first terminal and the second terminal are configured to be in contact with the first contact and the second contact, respectively, 
 wherein the light-emitting body is configured to be detachably fixed to the mounting portion by the magnet and the magnetic member, and 
 wherein a height of the spacer is higher than a height of the magnet. 
 
     
     
       7. The lighting device according to  claim 6 , wherein each of a height of the first contact and a height of the second contact is variable by contact between the light-emitting body and the first contact or the second contact. 
     
     
       8. The lighting device according to  claim 6 , wherein the magnetic member is fixed to the optical member or the sealing member. 
     
     
       9. The lighting device according to  claim 6 , wherein the sealing member comprises the magnetic member. 
     
     
       10. The lighting device according to  claim 6 , wherein the magnetic member comprises iron, cobalt, or manganese. 
     
     
       11. The lighting device according to  claim 6 , wherein a distance between the magnet and the magnetic member is less than or equal to 10 mm. 
     
     
       12. A lighting device comprising:
 a light-emitting body comprising an optical member, a sealing member, at least a first terminal and a second terminal, a light-emitting element sealed between the optical member and the sealing member, and a magnetic member; 
 a mounting portion comprising a magnet, at least a first contact and a second contact, a sliding mechanism of the magnet, an elastic body, and a switch, 
 wherein the elastic body is configured to distance the magnet from the magnetic member in the light-emitting body, 
 wherein the first terminal and the second terminal are configured to be in contact with the first contact and the second contact, respectively, 
 wherein the light-emitting body is configured to be detachably fixed to the mounting portion by the magnet and the magnetic member, and 
 wherein the switch is configured to supply power to the light-emitting body through the first contact and the second contact in accordance with a position of the magnet 
 
     
     
       13. The lighting device according to  claim 12 , wherein each of a height of the first contact and a height of the second contact is variable by contact between the light-emitting body and the first contact or the second contact. 
     
     
       14. The lighting device according to  claim 12 , wherein the magnetic member is fixed to the optical member or the sealing member.
